Ever since it was announced that Kate Middleton is expecting, there’s been much speculation over her due date and whether the Duchess is carrying twins.

St James’ Palace has put the rumour mill to bed today by releasing a statement that confirms her due date as being some time July and also that she’s expecting just one baby.

The Duchess of Cambridge's pregnancy was initially made public prior to the first trimester, whereas most couples usually wait until the start of the second trimester to announce that they are expecting.

But Kate and Wills were forced to reveal her condition earlier than planned after the 31-year-old was admitted to King Edward VII’s hospital suffering from severe morning sickness in December.

Initially Kate's treatment for hyperemesis gravidarum led many to suspect that she was expecting twins, as it’s more commonly experienced by women giving birth to more than one child.

The young Royal is believed to be approximately 13 to 14 weeks pregnant and it’s thought that this announcement from St James’ Palace confirming the birth month means that Kate has now had her 12-month scan.

A spokesperson for the Palace stated that Kate is feeling markedly better since she was discharged from hospital last month.

The Palace confirmed: “Their Royal Highnesses the Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in July.

“The Duchess's condition continues to improve since her stay in hospital last month.”

Typically hyperemesis gravidarum often eases up in the middle trimester, but the Royal family are taking no chances and the spokesperson confirmed that the couple are unlikely to undertake any new engagements in the next few weeks.

While Prince William goes back to work as an RAF search and rescue pilot, Kate will be resting and making sure that she takes care of herself.

Coincidentally if the royal baby arrives early he or she could potentially share a birthday with William’s mother, the late Diana Princess of Wales, who was born on the 1st July.
